<a name="GtkListStore.description"></a><h2>Description</h2>
<p>
The <a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a> object is a list model for use with a <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a>
widget.  It implements the <a class="link" href="GtkTreeModel.html" title="GtkTreeModel"><span class="type">GtkTreeModel</span></a> interface, and consequentialy,
can use all of the methods available there.  It also implements the
<a class="link" href="GtkTreeSortable.html" title="GtkTreeSortable"><span class="type">GtkTreeSortable</span></a> interface so it can be sorted by the view.
Finally, it also implements the tree <GTKDOCLINK HREF="gtktreednd">drag and
drop</GTKDOCLINK> interfaces.
</p>
<p>
The <a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a> can accept most GObject types as a column type, though
it can't accept all custom types.  Internally, it will keep a copy of
data passed in (such as a string or a boxed pointer).  Columns that
accept <a href="http://library.gnome.org/devel/gobject/unstable/gobject-The-Base-Object-Type.html#GObject"><span class="type">GObject</span></a>s are handled a little differently.  The
<a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a> will keep a reference to the object instead of copying the
value.  As a result, if the object is modified, it is up to the
application writer to call <em class="parameter"><code>gtk_tree_model_row_changed</code></em> to emit the
"row_changed" signal.  This most commonly affects lists with
<a href="http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-The-GdkPixbuf-Structure.html#GdkPixbuf"><span class="type">GdkPixbuf</span></a>s stored.

<a name="id954100"></a><h3>Performance Considerations</h3>
<p>
Internally, the <a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a> was implemented with a linked list with a
tail pointer prior to GTK+ 2.6.  As a result, it was fast at data
insertion and deletion, and not fast at random data access.  The
<a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a> sets the <a class="link" href="GtkTreeModel.html#GTK-TREE-MODEL-ITERS-PERSIST:CAPS"><span class="type">GTK_TREE_MODEL_ITERS_PERSIST</span></a> flag, which means
that <a class="link" href="GtkTreeModel.html#GtkTreeIter"><span class="type">GtkTreeIter</span></a>s can be cached while the row exists.  Thus, if
access to a particular row is needed often and your code is expected to
run on older versions of GTK+, it is worth keeping the iter around.
</p>
<p>
It is important to note that only the methods
<a class="link" href="GtkListStore.html#gtk-list-store-insert-with-values" title="gtk_list_store_insert_with_values ()"><code class="function">gtk_list_store_insert_with_values()</code></a> and <a class="link" href="GtkListStore.html#gtk-list-store-insert-with-valuesv" title="gtk_list_store_insert_with_valuesv ()"><code class="function">gtk_list_store_insert_with_valuesv()</code></a>
are atomic, in the sense that the row is being appended to the store and the
values filled in in a single operation with regard to <a class="link" href="GtkTreeModel.html" title="GtkTreeModel"><span class="type">GtkTreeModel</span></a> signaling.
In contrast, using e.g. <a class="link" href="GtkListStore.html#gtk-list-store-append" title="gtk_list_store_append ()"><code class="function">gtk_list_store_append()</code></a> and then <a class="link" href="GtkListStore.html#gtk-list-store-set" title="gtk_list_store_set ()"><code class="function">gtk_list_store_set()</code></a>
will first create a row, which triggers the <a class="link" href="GtkTreeModel.html#GtkTreeModel-row-inserted" title='The "row-inserted" signal'><span class="type">"row-inserted"</span></a> signal
on <a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a>. The row, however, is still empty, and any signal handler
connecting to "row-inserted" on this particular store should be prepared
for the situation that the row might be empty. This is especially important
if you are wrapping the <a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a> inside a <a class="link" href="GtkTreeModelFilter.html" title="GtkTreeModelFilter"><span class="type">GtkTreeModelFilter</span></a> and are
using a <a class="link" href="GtkTreeModelFilter.html#GtkTreeModelFilterVisibleFunc" title="GtkTreeModelFilterVisibleFunc ()"><span class="type">GtkTreeModelFilterVisibleFunc</span></a>. Using any of the non-atomic operations
to append rows to the <a class="link" href="GtkListStore.html" title="GtkListStore"><span class="type">GtkListStore</span></a> will cause the
<a class="link" href="GtkTreeModelFilter.html#GtkTreeModelFilterVisibleFunc" title="GtkTreeModelFilterVisibleFunc ()"><span class="type">GtkTreeModelFilterVisibleFunc</span></a> to be visited with an empty row first; the
function must be prepared for that.

<a name="GtkListStore-BUILDER-UI"></a><h3>GtkListStore as GtkBuildable</h3>
<p>
The GtkListStore implementation of the GtkBuildable interface allows
to specify the model columns with a &lt;columns&gt; element that may
contain multiple &lt;column&gt; elements, each specifying one model
column. The "type" attribute specifies the data type for the column.
</p>
<p>
Additionally, it is possible to specify content for the list store
in the UI definition, with the &lt;data&gt; element. It can contain
multiple &lt;row&gt; elements, each specifying to content for one
row of the list model. Inside a &lt;row&gt;, the &lt;col&gt; elements
specify the content for individual cells.
</p>
<p>
Note that it is probably more common to define your models
in the code, and one might consider it a layering violation
to specify the content of a list store in a UI definition,
<span class="emphasis"><em>data</em></span>, not <span class="emphasis"><em>presentation</em></span>,
and common wisdom is to separate the two, as far as possible.
